Polycarboxylate Superplasticizer Powder Type PCE Water Reducer ( NZY-P)

Naphthalene Sulfonate Formaldehyde (PNS)
(Na2SO4 ≤18%)

Description
PNS, a high range water reducer with no air entraining component, is also named as Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.. It complies with chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017.

Application
1. PNS is suitable to make autotrophic concrete, steam curing concrete, steel concrete and prestress concrete, all of which are made mainly of portland cement.
2. PNS is applicable in areas with the daily lowest temperature of 0℃ and for making concrete which requires high fluidity, high strength or steam curing.
3. PNS can be used to make C80 concrete with slump loss between 50mm and 70mm, or C60 concrete with that between 180mm and 220mm.
4. PNS can be used as a raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.
5. PNS is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.

Q:Need to do moisture treatment of the basement brick wall, masonry should choose what materials: Basement moisture, is to use a special material for moisture. Material to be persistent, if the kind of waterproof material, it is easy to fall off, so that the professional moisture-proof material in fact its effect is permanent. First, the ground special moisture-proof liquid is a professional moisture-proof material, and second, it is permanent because it is not done on the wall surface, it is sprayed on the wall after it will automatically penetrate into the cement layer, and the third it is environmentally friendly The top of the extravagant ga nong yellow domain fossil joint safety, it is inorganic matter without any volatile substances. Fourth, the cost is much lower than the waterproof material, as long as waterproof one-third of the material.

Q:Cement mortar label M. M7.. M. C. C25; cement grade C. C. C. C. etc., are used to which stage of the building, at the edge of the fool, Pile, beam and other general use of the number of cement, cement mortar are used where? More: Mortar labels are M. M. M7.. M. M12.. M. M. M. M. M40 several. Mortar according to the use of masonry, plaster, seams several, has nothing to do with the label. It must be said that the blame side of the uncle installed Jiao fat scorpion reckless words, can only be said that the high need to use high mortar strength of the place, and vice versa, really not very good explanation. C. C. C. C30 concrete graded cushion useful mortar is also useful C15 concrete, pile cap and so the best use C30 beam with C25 But this is not to say that this is the same, or depends on the parts you use, Its weight, the required strength and so on

Q:Brick and concrete structure and frame structure in the force system, the use of building materials and the scope of the three aspects of the difference. Thank you ~ ~ very anxious: Wind load transfer wall → foundation → foundation → crust Frame structure: gravity load transfer floor panel → secondary beam → frame beam → frame column → foundation → foundation → crust Wind load transfer wall → frame (assigned to frame column) → foundation → foundation → crust (Seismic level role with the same) masonry structure load-bearing materials for the block, cement mortar wall, concrete floor, foundation; frame structure load-bearing material for the reinforced concrete The scope of application varies according to the intensity of fortification in the area, the building height of the masonry structure is 21M or less, and the frame structure height is below 60M For details, see GB-2010 Code for Building Seismic Design

Q:18 layers of high-rise, frame-shear structure, the northern coastal areas, the external walls of real stone . wall materials with no burning hollow brick good? Do you want to use a red brick or a gray brick on every floor when you build a wall? If the direct puzzle does not have any impact, will not moisture it? What are the consequences of living in the world? . external wall insulation What is more popular in the north, the use of insulation board (such as polystyrene board) and insulation mortars have their own advantages and disadvantages? Also do the external insulation, the house is also used for insulation it? Is not finished pouring the wall after leveling is the rough room? More: 2 What kind of insulation room according to the state of the insulation requirements and materials can meet the requirements to meet Polystyrene board thin plaster can engage in energy-saving 65% or even higher requirements, and most of the foreign use, so more popular In addition, you said that the insulation mortar should be a kind of glass beads insulation mortar itself after the construction of the insulation effect, the mortar can achieve the effect of insulation is limited, if you meet the higher insulation requirements are either not applicable or Will be too thick construction can be But the efficiency of insulation, far less than the polystyrene foam insulation board For the external walls of the insulation, of course, the more insulation layer is more conducive to energy conservation, if conditions permit, do naturally good Generally speaking, the design will only design one of them, very few buildings inside and outside the building insulation are done inside and outside Pouring the walls have to build a layer of interface mortar, which can not be considered leveling, so that the basic can be the main work, and that is rough If the leveling is better

Q:External wall insulation with anti - cracking mortar but also with waterproof mortar Are the two materials the same? Only one okay?: 1. fresh cold water into the boiling pot to boil: because the faucet out of the water filled with air, you can fully guide the aroma of black tea, and overnight water, twice the boiling water or hot water bottle Not suitable for brewing black tea. 2. into the boiling water is boiling, to the way the warm pot and warm cup, to avoid the water temperature changes too much: the general shape of the teapot, have a chunky round pot body, is to make tea in the brewing when fully extended And dancing space.

Q:What is good for the waterproofing layer of the outer wall of the basement?: polystyrene foam board (ordinary or extruded board), construction attention to the backfill to be tamped, strictly prohibited the impact of rock damage to the foam board cement mortar protective layer, waterproof material is difficult to mortar surface, the lower the height can be used other such as wood, polyethylene foam membrane can also be used There are polystyrene board and masonry protection wall practice, masonry protection wall and waterproof layer between the use of Gongshi grams of grams of long-term Hinffe squeeze-type insulation polystyrene board, play anti-condensation and waterproof waterproof double effect

Q:Building floor moisture, please tell me about the building floor moisture, mainly want to understand the capillary phenomenon of building materials and prevention.: Do the construction map is not necessarily quoted atlas, in the design description of the wall" part of the following instructions can be: -0

Q:What is the wall gray? Is the mortar king or mortar the same?: Improve the mortar of the workability, water retention, cohesive force, so that the cement can maximize the hydration, thereby enhancing the strength of mortar, construction performance and effectively reduce the floor ash; completely avoid the gray paste (powder) after the construction of the second water The emergence of the burst of particles, cracks, for the construction of the surface to create a good base surface At the same time compared the use of traditional gray paste (powder) to reduce the cost of about 30% of the material Is in line with international low-carbon, energy-saving trend was environmentally friendly building materials

Q:Paste the culture of stone mortar into the construction site after the need to do material re-examination?: As for the mortar test block, then look at the side of the side of the side of the United States, some places require, and some do not require

Q:When using cement mortar, why is its bearing capacity lower than the same strength grade mixed mortar masonry masonry?: Mixed mortar fluidity and water retention by cement mortar much better, this point in the construction site has also been confirmed
